Attempts can be found in the DEA literature to identify returns to scale at efficient interior points of the production possibility set on the basis of returns to scale at points of the corresponding reference sets. However, an opposite approach is put forward in this paper, advocating that...

Strategic use of environmental information may have as consequence that a benevolent environmental agency will choose not to disclose information leading to reduced moral motivation. Thus, decision makers will not have access to such information, implying that they will not be able to adjust...

We use a two-period model to investigate intertemporal eff ects of cost reductions in climate change mitigation technologies for the power sector. With imperfect climate policies, cost reductions related to carbon capture and storage (CCS) may be more desirable than comparable cost reductions...

Recently, the world economy has seen its greatest down turn since World War II. Although not as bad as during the Great Depression, there was still a worrisome increase in protectionist measures, in an attempt to mitigate the economic downturn. Protectionism can have many different faces. It can...

Much analysis in macroeconomics empirically addresses economy-wide incentives behind consumer/investment choices by using insights from the way a single representative household would behave. Heterogeneity at the micro level can jeopardize attempts to back up the representative consumer...

It is increasingly observable that in different industries competitors jointly acquire and share customer data. We propose a modified Hotelling model with two-dimensional consumer heterogeneity to analyze the incentives for such agreements and their welfare implications. In our model the...

This study analyzes the stability of the distance coefficient values over time in the generalized gravity equation of Bergstrand (1989) using both aggregate and disaggregated trade flows among 22 OECD countries recorded for the sample period covering 1970 until 2000. We estimate the gravity...
